Setting the antenna gain to 20 dB reduces tx power to 10 dB, so the device thinks the total gain is 30 dB.
TX power is capped at 16 dB if the antenna gain is lower than 14 dB.
Current max reg power shows 30 but it never uses more than 16 as output tx power.
2.4Ghz is 29db , that’s correct.
Using lastest router os stable/beta no difference.
My guess is that you are using 80MHz as channel width, so you are also using frequencies in the range 5250-5330 capped at 24. Minus 8 of antenna gain (actually 7.1) becomes 16.
Have you tried to set channel to 5180 and/or to set the channel width to 20 or 40?
Found way to resolve this problem, first seems lower 5ghz band is limited to like 16db , middle is like 22 db and high 5.7+ is full power
Also United States as region is bugged and stuck at 16 db in whole range. Had to setup Lebanon as region so it started working on middle band (5.5ghz 20db and moving up to 5.7ghz is increasing up to 22db), then 5.7x ghz goes up to 27db (my phone had problem sometimes roaming on these high custom channels)
Channel width is no difference, tried all from 20, to 160mhz.
What did u mean with: Minus 8 of antenna gain (actually 7.1)
7.1 ros always count 8db antenna on 5.2 ghz ? Netmetal AX have no antenna included.
I think tx power suffers from 2 chains, thats 3db , at least it’s been for AC, not sure 100% about AX
TX-Power/channel settings have worst functionality ever seen on any wifi device. Selected country should filter channel width and then channel width should filter available channels with tx power info calculated.
I agree, the TX-Powers are somewhat random and the regulatory information does not match the reality on the device. I recently bought a new L11UG-5HaxD Routerboard, for building a custom indoor solution and this one skips the lower frequency channels 36-68 in the ETSI region (Europe). So i opened a ticket and they say this device is an “outdoor only device” and is by design so the indoor channels are disabled by default, mööööp, no information about this anywhere on the product or manual pages . Choosing other countries outside the ETSI region give me also a max of 16db, but in Germany we have a max of 23db(200mW) in the lower channels so i cannot max out the range with a 3dB Omni. Upper channels in Germany allow up to 1W and the board sticks at 22db on these channels.
Also setting the antenna gain has no effect to the result in any way with the current RouterOS version 7.15.2.
Mikrotik please fix this and update product pages!
I had a hAP AX3 do something similar, and a NetInstall fixed it.
It also developed other problems months later, and I consider it a defective now. WiFi doesn’t even work anymore, so keep that in mind. If a NetInstall doesn’t fix it, return it before it’s out of warranty.
NetInstall fixes tons of things that a factory reset does not. Use the 32bit version of NetInstall, 64bit gets blocked by automatic security stuff too often, causing all sorts of weird problems in Windows.
